Use of a modified Taber abrasion apparatus for investigating the complete stress state during abrasion and in-process wear particle aerosol generation

摘要

A present challenge in chemical nano-product formulation is the prediction of structure-function relationships of designed nano-particle based chemical engineering products such as coatings or solids. A particular attention is in this framework today paid to the question whether such products will release particles to the air during their life cycle. This aerosolization of (nano-) particles impacts possibly occupational and consumer health. A possible particle release mechanism here is simply wear, i.e. for example when holding, moving or walking on nano-functionalized products. This means that further to the study of aerosolization, today's chemical engineers need to be able to study wear, enabling them to make future products 'nanosafe by design'.
